HI Aman,
                Actually the configuration is a two step process.

First, we need to create a vrf-policy under router bgp like so
vrf-policy cust0
  label 1357


?    Shouldn't label be assigned automatically by the zebra label manager?

  nexthop 15.44.4.165


?    Does this next-hop apply to routes going out to CE? Or routes going to the core (other PEs and/or route-reflector)? Or both?


  rd 437:612
  rt import 452:424
  rt export 516:943
  exit-vrf-policy
!
vrf-policy cust1
  label 1730
  nexthop 171.40.184.82
  rd 66:33
  rt import 906:551
  rt export 890:543
  exit-vrf-policy
!
vrf-policy cust2
  label 32639
  nexthop 189.2.178.92
  rd 14:619
  rt import 904:272
  rt export 233:507
  exit-vrf-policy

Then you need to exit the router bgp configuration and add routes to a particular vrf using add command

add vrf cust0 10.30.40.89


?    What does 10.30.40.89 represent here?

thx
aman
